- Step 1: create_repo must always set private: false + auto_init: false
- Step 5: create_or_update_file content must be plain text — MCP handles
base64 internally; pre-encoding causes double-encoding (corrupted README)
Fixes intermittent bugs observed in CW-007 (display-catalog) and CW-013
(mpm-url-shortener) where READMEs were stored as base64 blobs and repos
were created private.
